The root file system is reiserfs which is built into the kernel, so no modules are required (I hope). When I boot, the screen clears and absolutely nothing else happens! Excellent stuff. I assume I have missed something basic but it is not obvious to me what.

Thanks to you both for the prompt answers, I will try both suggestions. But doesn't the thing issue any error messages?_________________"Ship me somewheres east of Suez, where the best is like the worst,

Removing the "quiet" and "console" parameters from the kernel line got lots of output. You get a mass of systemd and kernel messages until it reaches "Basic System target" and then it stops. After a wait you drop to a prompt and discover it has failed to mount the root file system. The VG is active, just nothing mounted, not dissimilar to genkernel. I will try tonight with lvmetad active._________________"Ship me somewheres east of Suez, where the best is like the worst,

The VG has not been activated. Any idea why not?_________________"Ship me somewheres east of Suez, where the best is like the worst,
